This package makes the native libs required for Wine's Faudio support, not external dlls to inject.
You can use your own faudio patches by putting them in the same folder as the PKGBUILD and giving them the .myfaudiopatch extension.
You can also revert faudio patches by putting them in the same folder as the PKGBUILD and giving them the .myfaudiorevert extension.
